SPECIFICATION forming part of Letters Patent 1%. 520,693, dated May 29, 1894. Application filed September 13, Isjea'; Serial No. 485.385. (No model.)

To all whom it may concern/.- t I Be it known that I, WILLIAM H. MILLER, of South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in S prinkler-I'Ieads for Street-Sprinklers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being'had to the accompanying drawings, and to the letters and numerals of reference marked thereon, which form part of this specification.

This invention is an improvement in sprinkf ling heads for street sprinkling machines, and its object is to so construct the head that it can be readily and expeditiously cleansed when desired, its interior being easily accessible without disturbing the valves. Also to divide the head into two or more chambers, respectively provided withjet apertures of difierent sizes, and with separate inlet valves, so that streams of different volumes can be discharged fromtheheadat the will of the driver of the machine, and according to the character of the surface being sprinkled;and the jet openings are so arranged (preferably) that the water will be ejected in vertical sheets, or planes at right angles to the machine, instead of in horizontal planes.

The invention therefore consistsin the novel construction and combination of parts hereinafter describedand claimed.

Figure 1 is a perspective view of a street sprinkling machine with my improved sprinkler heads attached. Fig. 2 is a perspective view of the sprinkler head detached. Fig. 3 is a transverse sectional view thereof, indicating the head opened by the aid of dotted lines. Fig. 4 is a longitudinal sectional view thereof.

In the drawings, A represents a valve chamber, or box, communicating through a pipe B'with the tank of the machine to which the sprinkler head is attached. This box is of any suitable construction, and is provided with two openings a, a, in its bottom, which are closed by valves 0, C, seated against annular valve seats 0, c, fitted in openings a, a, respectively. The valves are provided with stems (l which play through stuffing boxes (3 secured to thestop of box A and springs O interposed between the bushings G and the valves normally hold the latter closed. The

' :valves may be independently operated by means. of levers and connecting rods not shown, that extend to the seat of the driver at the front part of the machine and can be arranged to be worked in the ordinary manner either by hand or foot.

The sprinkler head D is almost cylindrical and is closed at both ends, but open at top, its open side being adapted to fit neatly and closely to the bottom of box A as shown in drawings. At one side of the head a bin e rod E is secured between projecting ears and the box A is provided with hook shaped earsA on the lower edge of its rear side, which are adapted to receive the ends of rod E, as indicated in Fig. 2, thereby suspending the head on the box, and hinging it thereto by a loose or detachable hinge joint, for when the head is swung down and back from under the box it can be raised so as to disengage rod E from ears A and be thus detached from the box. On the front side of the head, opposite ears d, are ears (1, between which is pivoted the end of a rod F, having a thumb nut f on its free end, and when the head is c1osed, as indicated in Figs. 1 and 2, the free end of said rod is swung up between ears A on the front upper edge of the box A, and nut f screwed down, so as to lock the rod and draw the head closely against the bottom of the box, as indicated in the drawings. A packing G of rubber or other suitable material is secured to the lower face of the box so that when the head is closed as indicated in Fig. 2 a practically watertight joint is made between them. i

The head is divided by a transverse partition D, into two chambers 1 and 2, one below each opening a, a, respectively, so that water can be admitted into the chambers independently by unseating valve 0, or O. The lateral or side walls of the head are perforated as shown, the perforations being more numerous at the outer and upper side of the head (adjoining rod F) than at the rear side, and furthermore the perforations for chamber 1 are larger than those for chamber 2. In practice the sprinkling will generally be done from only one chamber at a time, and the different diameters of the perforations enable the driver to vary the quantity of water ejected according to the requirements of the surface being sprinkled. It will furthermore be observed that the water escapes in vertical planes through the perforations in the head, and will sprinkle a narrow strip transversely of the machine as it is driven forward, thus obviating the annoyance incident to the employment of sprinklers using a horizontal discharge, by which the water is spread toward the sides and rear of the machine and apt to wet anything passing near to the rear of the apparatus, while my sprinklers having a vertical discharge will not throw water either in advance of, or behind, the sprinkler head.

Within each chamber 1 and 2, is arranged a diaphragm H, consisting of a curved plate, pivoted between the end walls of the chambers as indicated at h Figs. 3 and 4 so that it can be swung up to the position indicated in dotted lines Fig. 3. WVhen the head is unclosed these partitions underlie the valves, and receive the impact of the incoming water when the valves are opened and serve to divert the water so that it escapes with most force through the uppermost openings at the outer side of the chamber, while part of the water will escape around the end of the diaphragm and through the bottom and rear perforations in the head, with much less force however. In order to permit the lower end of the diaphragm to be raised the head is provided with a horizontal ledge or flange D at its rear upper side as indicated in the drawings,

against which the upper ends of the diaphragms press when the head is in operative position. As shown and described, the head is practically double, each part being provided with its own valve, so that it can be used independently, obviously however the head might have but one chamber, or more than two. To clean the head, rod F is loosened and the head dropped into the position shown in dotted lines Fig. 2, (the water being retained in box A by the valves therein,) and the diaphragms H are turned up thus rendering every part of the head accessible. If desired the head can be lifted from the box and after it is cleansed it is again hung upon ears A the diaphragms II drop into position by gravity, rod F is swung into place and secured, and the machine is ready for operation.

The detachability of the sprinkler head without disturbing the valves, or employing any tools, loosening of bolts, &c., and the ease with which it can be replaced, is of great practical advantage in this class of machines.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent thereon, isl 1. The combination of the head havinglateral discharge perforations, with a curved diaphragm pivoted in said head, substantially as described.
